Has anyone used letrozole for fertility and how effective?

Letrazole. Letrazole is probably as effective as Clomid (clomiphene) in inducing ovulation and probably better in patients with pcos. It is used off-label for this purpose but has some advantages over clomid (clomiphene). Does not cause thinning of the uterine lining, doesn't affect cervical mucus and induces a single follicle, so less chance of multiples and hyperstimulation.
